HAT.

l Specification of VLetters Patent.

Patented May 20,1913.

Application filed October 15, 1910. Serial No. 587,148.

To all 'whom t may concern Be it known that I, BERNARD NICHOLS, a citizen ot the United States of America, and a resident of Ravenna, county ot Por tage, and State of Ohio, have invented certam new and useful Improvements in Hats, of which the following is a specication.

My invention relates broadly to the prevention and cure of premature baldness. I

The object of the invention is the production of ahat which is adapted to it upon the head in such a manner as not to interfere with the free circulation of blood to the scalp, and at the Sametime so constructed asto be worn without discomfort., and without causing a temporary unseemly marking on the forehead or scalp of the wearer' where it comes in contact therewith, when the hat is removed.

Blood is normally supplied to the hair cells and skin of the scalpl by two main arteries on each side of the skull which. are branches of the temporal artery. Each of these branches, the anterior and the posterior temporal arteries, Aare again subd'b vided into two other large vessels, which lie close to the surface of the scalp and are but a short distance from the skull and which branch out into innumerable small vessels and capillaries permeating t-he scalp. My invention aims to produce a hat having de pressions in the contacting portions thereof which will lie over such of said vessels and thereby prevent compression of them, that the nutrition of the hair cells and skin is not materially lessened by its wear.

In the accompanying sheet of drawings which forms a part of this specification- Figure 1 is a side elevation of a head showing the chief 'arteries' which supply blood to the scalp, and a vertical cross-section `of a hat. made in accordance with my invention. Fig. 2 is a horizontal cross-section of a hat so made; land Fig. 3 is a vert-ical cross-section partly broken away illustrating a detail of my invention.

The temporal artery 1 branches into the anterior temporal artery 2 and the posterior temporal artery 3. The anterior' ten'xporal artery branches into a forward branch :t and a, rearward branch 5. poral artery branches into a forward branch and a rearward branch 7. In by far the The posterior tem? majority of heads the forward branch 4 of the anterior temporal artery crosses the normal line of contact of the hat with the head at a point approximately 50 degrees ot' arc from the anterior-posterial diameter of the head measuring from the front, and the rearward branch 5 crosses at a point approXimately 70 degrees of arc therefrom.

`The -forward branch 6 and the rearward branch 7 of the posterior temporal artery lie closer together than the corresponding branches of the anterior artery, and a point midway between them-crosses at' approximately 100 degrees of arcfrom that diameter measured in the same manner.

The hat-band 8 has depressions 9, 10 and 11 at .these points respectively, which depressions are of suilicient width to allow for such deviation from these points as are likely to occur in the position of the branches 4, 5, 6. and 7 among normally shaped heads. These depressions are conveniently made by raising those portions of' the bandadjoining them and backing the vraised portions with felt 12, 13 and 14.

To compensate for the varying pressure due to the different degrees of tightness with which hats are worn, and to assure that the rear walls of the depressions 9, 10 and 11 will never be brought into harmful contact with the scalp, these pieces of felt may conveniently be made tapering from the top to the bot-torn. This adds greatly to the appea'rance of the hat as the resilience and thickness of the felt can be so gaged that the hat-band appears to be in contact with the head at all points while the actual Aweight and pressure is avoid the vessels 4, 5, 6 and 7. The felt backing 12 may conveniently have an additional sidewise taper in a direction away from the adjoining depressions yvhich form the band at the front and the rear of the hat.

While I have particularly described my invention as applied to a hat-band it is to be understood that I do not intend to limit it thereto, my invention beingadapted to all manner of head-dress intended to fit the head whether with or without a band. Nor do I intend to limit myself to the series of depressions for my invention contemplates `the adjustment of the .pressure upon so distributed as to' all manner of head-dress intended to fit the end rear protrusions tapering toward the to the scalp is not interfered With.
